APPARATUS FOR FEEDING'AND CONSUMING FINE FUEL..

SPECIFICATION forming part of Letters Patent NJ. 292,237, dated January 22, i854.

Application filed August To @ZZ whom t may con-cern.-

Be it known that I, JULIUs LEEDE, 4a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Apparatus for Feeding and Consuming Fine Fuel; and I do hereby declare the following invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a process of consuming, and to an apparatus for feeding, igniting,

consisting of pulverulent earthy substances, coal,or sawdust mixed or saturated with petroleum or other hydrocarbon; and `it consists in a process of burningr hydrocarbons, which consists in mixing the same with granular or pul.- verized material, feeding it to a furnace,'and scattering, igniting, and consuming it while in suspension; in the combination of an automatic feed and means for producing a blast, and for .igniting the fuel as it is 4projected away from the feed-tube by the blast; in the combination of a blower, a carburetor, and a throughout the chamber and suspending it during combustion, as well as for supplying oxygen for combustion; in the combination of aseries of blast-pipes and means adjacent thereto for igniting the fuel as it escapes and enters the fire-chamber; the combination of a series of adjustable pipes and gates and valves for controlling the direction, force, and quantity of the blast without changing the speed of the blower; and, further, my invention consists in certain combinations of details, which will be hereinafter more particularly described aand claimed.

In the accompanying drawings, making a part of this specification, Figure 1 is a front elevation of my apparatus for feeding and consuming pulverized or compound hydrocarbon fuel. Fig. 2 is a side elevation of the saine. Fig. 3 is a sectional end elevation fronrthe side opposite the view in Fig. 2, showing a plurality of blast-pipes and their valve and lever connections. Fig. 4 is a vertical sec- 30, 1883. (No model.)

tion of the fuel hopper or reservoir, specially 5o showing arms proj ecting from a revolving ver.- tical shaft located in the center thereof, for stirring and agitating the'4 fuel. '`Fig. 5 is a 'vertical section of the carburetor forming a part of the apparatus. Fig. 6 shows the ap- 55 plication of the apparatus to a locomotive, and illustrates a means of removing the dbris from the fire-box thereof. A is a blower of any suitable construction, a Root blower being preferred. Thisblow- 6o er is provided with a relief-valve, a, so that the blast through the tubes may be partially cut oft without changing the speed of the blower. l

B is the air-trunk, from which the blasttubes bb lead to the mouth of a fire-box or furnace. These blast tubes are connected with the trunk by dovetail bases b b.

b2 b2 are levers which operate valves in the trunk for regulating the blast through the pip es 7o without changing the speed of the blower.

G is a carburetor, consisting of a vessel having a pair of wheels mounted therein, and havin g yarn or other fibrous material stretched diagonally across from one to the other. These wheels, interlaced with yarn, constitute an agitator, G', .which tends to keep the gasoline in suspension while the air is forced through the vessel.

g is a pipe leading from the air-trunk to the 8o carbureting-vessel, and g is the exit-pipe, leading from the carburetor to the mouth of the furnace or fire-box. This pipe is provided with a gas-cock for shutting off the flow of gas, and thereby extinguishing the re in the furnace. It is also provided at its extremity with a lip orv fender, x, to guard against extinguishing the Iiame by the force of the blast from the blast-tubes, and with perforations z just below the mouth or burner,througl1 which 9o the gas escapes and ignites, and thereby operates as priming-j ets to' relight the main flame in case it may be accidentally extinguished.

A flexible branch pipe, g?, leads from the'pipe g', which I use as a lighter for the gas within 95 the furnace.

K is a driving-pulley, to which power is applied for operating the blower, and from which motion is imparted to the different moving parts of the machine.

H is a gasoline-tank secured', for convenience, to the side of the hopper E, having a conduit, h, leading to a carburetor for replenishing the same whenever required. The amount of gasoline in the carbureting-vessel is convenient-ly indicated by a gage, 3,'.

E is a hopper for containing a quantity of pulverulent compound fuel, or of pulverulent earthy material, saturated with hydrocarbon, and it is provided with rotating mixers or stirrers e e, to preventthe fuel from clogging within the hopper. Leading from the base of the hopper is a conduit, c c* c, through the branch c of which the fuel is fed by a screw-com'eyer, I, whence it drops by gravity through the branch ci, and is then, by another like screwconveyer, delivered to the mouth of the furnace. This latter conveyer does not quite reach to the end of its casing, and has attached to its extremity, next to the furnace, an cecentric pin, to break up any lumps which may have formed in forcing the material forward. The arbor of this conveyer is also made hollow, and has a pipe, li, leading from the airtrunk, or from a source of steam or earbureted air, so that the stream of fuel will be broken and spread as it issues from the conduit c, to be caught by the blasts from the tubes b b. Shafting L, M, and N, mounted in suitable frame-work upon or above the blower, carry reciprocally-diiferential and inversely-graduated series of sprocket-wheels, carrying chain belts, and shaft M has a series of clutches mounted thereon, operated by levers m m, for throwing either of the sprocket-wheels and its corresponding chain into operation.

O is a hood arranged to protect the gearing for the stirrers c c.

The operation of my apparatus is as follows: The hopper being charged with fuel, and the carburetor with gasoline, power is applied to the pulley K, the blower is put in operation,

and through the chain belt p the shaft Ijis revolved, and through one of the chains p p p p the shaft lll, through gearing r, causes the conveyer I to force lthe fuel from the hopper E, and the shaft X, through gearing r, drives a screw-conveyer in the conduit c, and delivers the fuel to the mouth of a fire-boxer furnace. rlhe shafts carrying the fans of the blowers are geared together, and a sprocketwheel mounted on one of these shafts operates chain belt p2, and, through shaft l and gearing vrotates the stirrers c c. The shaft 1",tlnfough belt p, drives the agitator G in the carburetor. At the same time blasts of air are driven through the pipes b b I) b to the furnace, for scattering and supplying oxygen to the fuel, and through pipe g into the carburetor, whence it issues by pipe y to supply gas for the jet-fiume, and by the pipe c" through the arbor of the conveyer in conduit e3, to break up and separate the'column of material fed forward by the conveyer.

Fig. 6 shows the application of my invention to locomotive-boilers. This figure shows a machine located in the cab, with the blastpipes projecting into the furnace. The use of this apparatus renders grate-bars unnecessary.

In lthe furnace shown, a coucaved or hopper bot-tom is made for receiving and concentrating the uneonsumed infusorial earth. This uneonsumed portion or vehicle for the fuel may be removed from the furnace by means of a suitable conveyer, as shown, to a receiving-bin on the tender.

It is obvious that the particles of earth saturated or surrounded by the hydrocarbon, upon being separated by a blast, will divide the same into minute parts, so that the oxygen has access to and entirely consumes it.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The method herein described of burning hydrocarbons, consisting in mixing the same with granular or pulverized material, feeding it to a furnace, and then simultaneously scat-- tering and igniting the same, and thereby eonsuming it while in suspension, as set forth.

2. rlhe combination, substantially as described, of a carburetor and a blower having a blast through the carburetor tothe furnace, to provide gas and pressure for a jet-flame, and a separateblast to the furnace, substantially as and for the purpose described.
